The first update to come to the app since the launch of iOS 7 in September last year, ListBook 4.0 unsurprisingly introduces a new design that matches the look and feel of the operating system. It also adds support for sharing via the iOS 7-only AirDrop method. Moreover, it comes with six color themes to customize the app with.

But perhaps most importantly, the update adds a highly requested feature in the form of iCloud sync. Considering that ListBook is a universal app for iPhone, iPod touch, and iPad, iCloud sync is a great addition to ensure that to-do, shopping, and other lists are always up to date across multiple devices.
